请你看看这个css snipet,让我知道为什么我无法将跨脉冲和fadeout动画角色添加到跨度?

从技术上讲,我喜欢在一个动画中同时使用或者同时接受脉冲和淡出动画



html,body {
   height:100%;
   width:100%;

}
#point {
   height:100%;
   width:100%;
position:relative;
}


.pulse {
  position:absolute;
  margin:30px;
  display: block;
  width: 22px;
  height: 22px;
  border-radius: 50%;
  background: #cca92c;
  cursor: pointer;
  box-shadow: 0 0 0 rgba(204,169,44, 0.4);
  animation: pulse 2s infinite;
}
.pulse:hover {
  animation: none;
}

@-webkit-keyframes pulse {
  0% {
    -webkit-box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
  }
  70% {
      -webkit-box-shadow: 0 0 0 10px rgba(204,169,44, 0);
  }
  100% {
      -webkit-box-shadow: 0 0 0 0 rgba(204,169,44, 0);
  }
}
@keyframes pulse {
  0% {
    -moz-box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
    box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
  }
  70% {
      -moz-box-shadow: 0 0 0 10px rgba(204,169,44, 0);
      box-shadow: 0 0 0 10px rgba(204,169,44, 0);
  }
  100% {
      -moz-box-shadow: 0 0 0 0 rgba(204,169,44, 0);
      box-shadow: 0 0 0 0 rgba(204,169,44, 0);
  }
}
.hideMe {
  -webkit-animation: seconds 1.0s forwards;
  -webkit-animation-iteration-count: 1;
  -webkit-animation-delay: 5s;
  animation: seconds 1.0s forwards;
  animation-iteration-count: 1;
  animation-delay: 5s;
 
}
@-webkit-keyframes seconds {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
    left: -9999px; 
  }
}
@keyframes seconds {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
    left: -9999px; 
  }
}

<span class="pulse hideMe"></span>

您正在使用。秒动画覆盖.pulse动画。您需要在同一个关键帧集中包含两个动画,或者在animate属性上用逗号分隔关键帧集。或者,您可以使用包装器,将fadeout放在包装器上,将脉冲放在实际跨度上。 Css属性彼此不“堆叠”,它们被后面的实例替换,对于动画也是如此。
